Upgrade unified deps and improve unified plugins types (#1200)
* Upgrade @astrojs/markdown-support deps and update types

* Add changeset

* Update changeset

* Switch astro-markdown-plugins example to use rehype-autolink-headings

Usage of remark-autolink-headings is discouraged in favor of the rehype counterpart: https://github.com/remarkjs/remark-autolink-headings\#remark-autolink-headings

* Add stricter types for unified plugins

This includes a few suggestions from a code review:
- use vfile.toString instead of vfile.value.toString
- refactor plugins to follow unified best practices instead of returning functions that return a plugin
- use any instead of any[] for plugin options types

* Narrow down types to more specific hast or mdast typings
